Njengoba ibanga physics? izibonelo ezithakazelisayo

Isihloko Sizokwenza labo abafundi kuphela onyakeni wokuqala physics. Lapha sikhuluma hhayi kuphela mayelana nokuthi ibanga kuyi-physics, kodwa futhi mayelana nezinye izinto ezithakazelisayo. Ake le nto kube nentshisekelo zonke izigaba kanye nezihloko.

Kuyini - ibanga?

Ngo-physics, njalo ubuningi ngokomzimba has uphawu ayo (noma isiLatini, noma incwadi ngesiGreki). Konke lokhu kwenziwa ukuze wenze kube lula futhi kugwenywe ukudideka. Vumelana kungenziwa isiphelile uma ubhala incwadi mayelana imishwana enjengethi: ibanga = Isivinini x isikhathi. A physics amafomula eziningi kakhulu ezahlukene sebuningini nemingcele. Kukhona amagugu isikwele cubic. Ngakho yini incwadi isho Ibanga physics? Ngokushesha ucacise ukuthi kunezinhlobo ezimbili kwezimpawu njengoba ibanga nobude kukhona usayizi ofanayo futhi iyunithi efanayo. Ngakho, «S» - lena uphawu. Ukuze kuhlangatshezwane incwadi anjalo esikhathini puzzle, noma amafomula kusukela kusigaba "Mechanics".

Believe me, akukho nzima ekuxazululeni izinkinga. Kodwa inqobo nje uma wazi izibalo, futhi sibe nesikhathi ke. Uzodinga ulwazi kwemisebenzi enamafrakshini, nekubala, ukudalula kubakaki, nokuxazulula izibalo. Ngaphandle lamakhono kuyoba nzima kakhulu kwi-physics.

izibonelo Life

Kuyini ibanga? Njengoba ibanga kuyi-physics, siye wakwenza kwacaca kakade. Manje ake ukubhekana umqondo.

Zicabange emi phambi kwendlu yakhe. Umsebenti wakho - uma beya esikoleni. Umgwaqo ngqo ngaso sonke isikhathi. Ukuya kusuka amandla mayelana imizuzu emibili. Kusukela umnyango nomnyango iminyango esikoleni 200 amamitha. Lona ibanga. incazelo ukuhamba kwakho ekhaya esikoleni ngeke kanjani?

S = 200 m.

Kungani sibhala "m", futhi kuphela nomkhawulo incwadi? Ngoba nakhu lo esifushanisiwe incwadi isiqu. Ngemva kwesikhashana, owazi nemingcele okuhlotshaniswa ibanga.

Manje zicabange indlela esuka endlini ukugcina tortuous. Uma ubheka ibalazwe endaweni yakho, uzobona ukuthi ibanga kuyafana ngaphambi esikoleni ukuthenga ekhaya. Kodwa kungani indlela eside kangaka? Ngoba endleleni ayiqondile. Kufanele udlulele e-amarobhothi, uthole indlu omkhulu futhi kufanele nje ufika esitolo. Kulokhu, ibanga langempela likhulu kakhulu. I-geometry yemvelo, lokhu kubonisa a "endleleni lwalugobile." A umugqa oqondile - kungcono nje ibanga okuhlanzekile, njengoba uma uhamba udonga endlini enkulu. Singasho futhi akunike isibonelo, kepha umuntu uya emsebenzini.

Kwaba namuphi ibanga?

Nombono wokuthi "ibanga" ngeke kube khona lodwa, kumele ibambe iqhaza. Ngokwesibonelo, ukuhamba ngebhayisekili esikoleni futhi musa ukuhamba ngezinyawo, ngoba emva kwesikhathi. Njengoba sishilo phambilini, ohambweni lwethu ukuqondisa esikoleni. Ungakwazi ukugibela ngokuphepha eceleni komgwaqo. Yiqiniso, uma uzulazule ngezinyawo, uthola isikhathi eside kunaleso ukwenza ngebhayisikili emgwaqweni. Yin'indaba lapha? Yiqiniso, ukukhuluma ijubane ngawo abahambayo. Kamuva sizobona amafomula ukuthi ngokushesha, indlela yokuthola ibanga. Physics - kuyinto isayensi, okuyinto unokuthile ukubala. Ngiyavuma, kuyathakazelisa okusheshayo nje indlela ukuhamba ngebhayisekili? Uma wazi ibanga esikoleni futhi abahambayo, uzothola kanye nesivinini.

Ngakho, saba nezinye izinketho ezimbili:

t - isikhathi,

v - velocity.

Konke kuyoba mnandi kakhulu uma ufunda ukusebenza amafomula ukuthola engaziwa ngokusebenzisa izingxenyana zaso. Khumbula ngokushesha njengoba umthetho wezibalo: konke leseceleni engaziwa, kuba zihilela (ie, Izingxenyana phansi). Ngokwesibonelo, ifomula ibanga (Physics) - umkhiqizo isikhathi kanye nesivinini. Futhi kwezinye izimo - ingxenyenamba. Buka lesitfombe, esibonisa indlela ukuthola ibanga, isivinini kanye nesikhathi. Ngempela kube abaqeqeshiwe futhi uqonde ukuthi onjalo amafomula etholakala. Zonke kufanele kube kusuka imithetho wezibalo kuphela, yasungulwa akukho lutho kulemibandela amafomula ungapheli. Ake thina umkhuba (ayibukeki): Yini incwadi isho Ibanga physics?

Yini kukalwa?

Sethemba, oyikhumbulayo ekubizweni nenani eziyisisekelo, isiqu sabo. Sekuyisikhathi bafunde amayunithi wokulinganisa angakahleleki. Kuzoba futhi sibe Ukuqeqesha inkumbulo yakho, khumbula. Kubalulekile ukwazi ukuthi indlela ibanga kuyi-physics, kodwa futhi isikhathi, isivinini. Kodwa lena kuphela udaba encane. Okulandelayo kuzoba nzima. Asiqale:

S - ibanga - m, km [m] [km];

v - isivinini - amamitha ngomzuzwana, ingamakhilomitha angu-ngehora [m / s], [km / h] (uma isikhala velocities kungenzeka ikhilomitha isicelo ngesekhondi;

t - isikhathi - eyesibili, ngomzuzu, ihora [c] [imiz] [h].

Phawula indlela ijubane okhethiwe. Kahle, ingxenyenamba. Manje zicabange lapha: S / t = m / noma S / t = km / h. Kulapho lapho badutshulwe. Esikhathini kohlelo lamazwe omhlaba amayunithi SI amagugu yalezi nemingcele abe imitha, yesibili, amamitha ngomzuzwana.

Thina esiphethweni kanjani ibanga kuyi-physics, kubhekwa isikhathi kanye nesivinini, okuyinto kuhlobene ngokungenakuhlukaniswa ke.
